I guess this has something to do with keeping your phone number even when switching providers? We got a law in Norway around that time, which says you're able to keep your phone number while switching. Only difference is that here you can only tell, from the first two of eight digits, which ''provider'' you had in 2005 (or whenever it took effect). --[[User:Buggz|Buggz]] ([[User talk:Buggz|talk]]) 08:31, 2 November 2012 (UTC)

Revision as of 05:16, 7 November 2012

In the explanation: "The next three digits are the exchange number (the middle digit being always 2 or higher)". That cannot be true. After my area code, my exchange number is 504...the middle digit being a zero i.e. <2. Where did you get the information that the middle exchange number has to be a 2 or higher? That source should be corrected as well See This Link.--Dangerkeith3000 (talk) 17:13, 5 November 2012 (UTC)

It probably does. There is no mention of 2005 in North American Numbering Plan wikipedia article ... seems it's the part needing explanation the most. -- Hkmaly (talk) 08:38, 2 November 2012 (UTC)
According to wikipedia, mobile number portability was implemented in the USA in 2003.11.24. The comic would make sense with 2003, but why 2005? Maybe it only caught on enough in 2005: http://www.pyramidresearch.com/pa_may26_mnp.htm
One reason for switching to a new "local" number would be so that those who have land lines aren't making "long-distance" phone calls to your cell phone. My brother just recently moved back from the east coast and is keeping his same cell phone number, which doesn't affect my other siblings and myself because we only use cell phones (which only count the number of minutes used). But my mom still uses land lines most of the time and so she's being billed for a long-distance call whenever she calls him, even though he lives about a mile away from her. But since most people are ditching the land lines, I think it'll be a moot point in about 5-10 years. --Joehammer79 (talk) 13:45, 2 November 2012 (UTC)

It has to do with cell phones versus land lines. Back in the day (before the early 2000s), many people still had a land line as their primary or only phone. Your phone number's area code would be based on the area in which you lived. If you moved to a new area, you would get a new phone number, and if you moved out of the previous area code, a new area code. But with a cell phone, when you moved you kept the same number, including the area code. This was especially true after the 2003 law made it so you could keep the same number even if you switch your provider. The year 2005 has to do with when many people made their cell phone their primary or only phone. As this USA TODAYarticle mentions, in 2003 18% of Americans with cell phones considered their cell phone their primary phone. Given the rapid growth of the industry, it is possible that 2005 is when more than half of cell phone owners in America considered their cell phone their primary phone.

The details differ, of course ("your mileage may vary"). There are so many possible reasons why this occurs. My parent's cell phones (612) don't match their home land-line (763) due to area code splits -- they didn't move or cause the disconnect themselves. As for me, my first cell phone matched theirs, but in 2005 I moved to Michigan (586 area), creating a disconnect. Then to make things worse, early next year (2006) I got a second line (and new phone) on my new girlfriend's account, and she lived on the other side of the city (734). We married and moved near where I was living & working, but both still have "734" cell phones for family purposes. So Randall's "living" can also be "dating / where significant other is living". --BigMal27 / 192.136.15.149 15:54, 2 November 2012 (UTC)

For anyone from outside the US, the key fact here is that in the US, your mobile phone has an area code the same as a landline. I used to live in the US, and it blew my mind to learn that mobile phones had area codes there. I was like, but.... Huh? That's like saying your car has a postal address.Carlisle (talk) 15:06, 2 November 2012 (UTC)

In the US, our cars kind of do have a postal address -- the state they are titled & registered in, the same state emblazoned on the license plate in the back (and sometimes the front also). However, the states don't like it when you operate an "out-of-state" car in their territory for too long. Specifically, you are using public roads that you are not paying for. Then, when you transfer title and are assigned a new plate, you get a new letter/number combination. License plates -- and specifically the random ID (or "vanity plate" custom ID) they hold -- are not portable between states. --BigMal27 / 192.136.15.149 15:47, 2 November 2012 (UTC)
In the past, in Italy you had to do the same when you moved from one province to another. Now, if you move, you pay car taxes to a different province, but your license plate stays the same. At the time, the province code was part of the license number, now it isn't anymore. If you have an old plate with a province code, you keep it even if you move.
If you have an out-of-country car, and move to Italy for more than a year, then you have to get Italian license plates.

In Poland the license plate starts with three letters encoding the county (voivodeship and powiat) --JakubNarebski (talk) 10:28, 3 November 2012 (UTC)
In the UK the first two letters on a car's plate are for where it was registered, but after that they may as well be meaningless, you do see more S plates in Scotland, M plates in Manchester etc. but the letters don't always even indicate the car was bought as new in that place, I take photos for car dealers and you often see new cars for sale with plates from other parts of the country. Still, actually being able to post to a car would be funny.
On the subject of postal addresses, I had an Irish friend at uni, and when we were exchanging addresses to write to each other at the end of first year he gave his address as (not his real name, obviously) Sean Murphy, Kilbeggan, Ireland. We all laughed but he said, the postman knows who everyone is so they don't need street names and numbers, we asked what if they got a new postman, and he said 'that wouldn't happen'.Carlisle (talk) 23:10, 4 November 2012 (UTC)

I'm 34 and live in the USA and it still took me a while to understand this. The 2005 date is because even though the portability law was passed in 2003, it was still difficult to do and not very common to keep you number until 2005.

Handi phones

"cell/mobile/handi phones" ... Who uses "handi phones"? Would be really interesting :) --Kronf (talk) 02:18, 3 November 2012 (UTC)

A German friend tells me that that is the term of art for what US folks call "cellular" phones: "Ruf mich am Handi an," (in my broken German: "call me on my handi/cellphone") Given that we've got an international audience, it seemed appropriate to use. -- IronyChef (talk) 02:31, 3 November 2012 (UTC)
Ah ok. And you had me thinking that someone in the English speaking world was using our German term ;) --Kronf (talk) 02:43, 3 November 2012 (UTC)
But we write it "Handy" ("Handi" (with a german "i") is how you speak it – the letter "y" can be a "i"- or a "ΓΌ"-sound in German). --DaB. (talk) 16:32, 3 November 2012 (UTC)
I stand corrected, then... -- IronyChef (talk) 04:36, 4 November 2012 (UTC)
